A Harrogate clinic is offering a private saliva test for women with suspected endometriosis.
Cocoon Healthcare, on East Park Road, says patients can expect results within 25 days.
The test, called EndoTest, costs £1,100. Patients give a saliva sample at the clinic, which sends it away for analysis.
James Tibbott, a consultant gynaecologist and endometriosis specialist, will review the results and advise patients on next steps.
Endometriosis affects around one in ten women. It occurs when tissue similar to the lining of the womb grows elsewhere in the body.

Sam Naughton founded Cocoon Healthcare in 2024.
Symptoms can include pelvic pain, heavy bleeding and periods painful enough to disrupt everyday life.
A survey published by Endometriosis UK in March found that respondents waited an average of nine years and four months for a diagnosis.
In a separate survey by the charity and Cysters, respondents from ethnically diverse communities reported an average wait of 11 years.
Sam Naughton, who founded Cocoon after experiencing baby loss and pregnancy-related anxiety, said:
“Nine years is an extraordinary amount of time to spend wondering why you're in pain.
"Just imagine everything that can happen in nine years, and then imagine spending that entire time worrying about your health, missing important moments, struggling through work or wondering whether you'll ever get an answer.
"It's heartbreaking that this is the reality for so many women.”
She added:
“Nobody should be made to feel that debilitating periods or persistent pelvic pain are simply something they have to put up with.
"When a woman says something isn't right, she deserves to be heard and taken seriously.”
